Agree with the line of reasoning that changing one's mind is not necessarily a bad thing, it depends on the reasoning behind it. If it's the usual vote-trolling flip-flop, bad. If it's a change based on new information, exposure to different viewpoints and logic, that's good, it shows the ability to grow and think.

The ability to change one's mind and make informed decisions is a plus in my mind. It's better than "staying the course" when that course takes you straight into a hurricane.
